Okay, let’s calculate this. James has a broad range of skills, including R&D, systems engineering, and product development, which are in demand across various industries. His experience in Matlab and robotics also adds value. Considering his location in Baltimore, MD, and the current market demand for engineers with these skills, I estimate his hourly rate to be around $125. This is slightly below the national average for engineers in the US, but takes into account his specific skillset and location.
